The Federal Employee: Making the Most of FERS, TSP, and a Pension
Federal workers have a rare three-legged stool — a pension, a low-cost TSP, and Social Security. Here's how to get every leg right.
Executive Summary
Federal employees under FERS have something most Americans no longer do: a genuine three-legged stool — a defined-benefit pension, the low-cost Thrift Savings Plan (TSP), and Social Security. The opportunity is real, but several decisions — the survivor election, TSP allocation, and what to do with the TSP at retirement — quietly make or break the plan.
01The Three-Legged Stool
FERS combines three sources: the FERS pension (a guaranteed monthly benefit based on years of service and salary), the TSP (a 401(k)-style account famous for ultra-low fees), and Social Security.
Coordinated well, these three can produce a secure, largely guaranteed retirement. The details are where federal employees gain or lose.
02The Survivor Election (and Health Coverage)
One of the most consequential FERS choices is the survivor annuity. Electing it reduces the pension while you're alive but continues income to your spouse after you pass — and, critically, it is typically tied to your spouse keeping FEHB federal health coverage as a survivor. Declining the survivor benefit to get a bigger check can leave a spouse without both income and health insurance. For married employees, this deserves careful, joint thought.
03The TSP Decision
The TSP's superpower is cost — its fees are among the lowest anywhere, so rolling money out of it should never be automatic. At the same time, the TSP's investment menu is simple (the G, F, C, S, and I funds), and some retirees want guaranteed lifetime income or strategies the TSP doesn't offer. The balanced approach: keep the low-cost core where it serves you, and consider moving only the portion that needs guarantees or features the TSP lacks.
04Sequence Risk and the G Fund
The TSP's G fund offers principal stability, while the C, S, and I funds carry market risk. As retirement nears, managing the mix matters: too aggressive, and a crash in the first retirement years (sequence risk) can do lasting damage; too conservative for too long, and inflation erodes purchasing power. Pairing a guaranteed-income floor with growth assets is the same balance seen throughout these studies.
05Educational Takeaways
- FERS is a rare three-legged stool — coordinate the pension, TSP, and Social Security.
- The survivor election protects both a spouse's income and their health coverage.
- The TSP is very low cost — don't roll it out reflexively; move only what needs guarantees.
- Manage sequence risk as retirement nears.
Federal employees have a rare, powerful setup — but the survivor election and TSP decisions quietly decide how secure it really is. Get those right and the three-legged stool holds.
06Questions Clients Should Ask
Should I take the FERS survivor benefit?
For married employees, usually it deserves strong consideration: it continues income to your spouse and typically preserves their FEHB health coverage. Declining it for a bigger check can leave a survivor without income and insurance.
Should I roll my TSP into an IRA at retirement?
Not automatically. The TSP's fees are exceptionally low, so keep the low-cost core where it serves you. Consider moving only the portion that needs guaranteed income or features the TSP doesn't offer.
How do I handle market risk in the TSP near retirement?
Balance growth (C, S, I funds) with stability (G fund) and consider a guaranteed-income floor, so a downturn in your first retirement years doesn't do lasting damage.
